Question

How many spermatogonia are required to form 20 embryos​

Answer 1

In mammals, gametogenesis ultimately requires that diploid germ cells undergo the process of reduction division known as meiosis to form functional gametes. However, oogenesis and spermatogenesis occur at very different times during development and achieve different endpoints. In females, this process is initiated in the fetus well before birth, with the goal of forming a finite number of stored gametes that are used periodically over a defined reproductive lifetime. In males, meiosis is not initiated until postnatal life at the onset of puberty, and the goal is to form the millions of gametes required for male fertility (
